We need to conserve land and soil for several reason. The soil is the home to many creatures such as earthworms etc. We need to conserve soil to prevent floods, this is becasue if it rains to heavily and there is no soil to absorb the rain the floodinf will result. We also need land and soil to sustatin plant growth and since plants are producers and are at teh start of the food chain, we need plannts for survival.

Where does soil come from?
What is it good for?
What are the effects of running out of useable soil?
It takes ~100 years to create 1 inch of topsoil.
In some places that's how much is washing down the Mississippi river every year.
Tillable soil is required for farmland. Today, must manufactured goods are made in China. Since suburbs have been allowed to be built over a great deal of prime farmland in the last 60 years, are we on our way to importing most of our food from other countries as well? Isn't this an important national security issue, as well as an economic & political one?
There are a lot of angles to work this. Keep looking.
Good Luck!

It is extremely important to protect the land and soil. The soil has several layers of vital elements. When a piece of land is used to grow any type of crop, when is harvest time the land looses some of its elements. It is important to use rotary harvesting letting a piece of land regenerate before planting again.
If the land is over used then the harvest wont be successful and chemicals are used to prevent this, this chemicals drain through the land, contaminating underground reservoirs of water.

All life on our planet begins in the soil and the water. We are dependent upon the microbes of the soil for everything. If we think of dirt as just sand and rocks ground up, we miss half the life of our planet. Every plant you see has its equivalent underground to support it, and a host of bacteria and fungi to help minerals and water get absorbed by the roots.
Soil is more important than oil.
